polar coordinates and centre of mass

Use polar coordinates in the plane to show that the area of a disc of radius a is ∏a^2.
Using this result, determine the volume of a cone of height h and radius a.  Find the position of its centre of mass.

Re: polar coordinates and centre of mass

And we could do a triple integration to find the center of mass, but I am not really good at the calculation lol
